Feign would I select one instance of muscular organization so striking, that the mind should be immediately sensible of the thought, the care, and the tenderness of the Divine Contriver. Though the following is by no means a solitary instance, yet still it is, without doubt, a satisfactory illustration.

The foot is placed at a considerable angle with the leg. It is therefore obvious, that flexible strings, passing along the interior of the angle, if left to themselves, would, when stretched, start from it. The obvious preventive is to tie them down. And this is actually done: just above the instep is placed a strong ligament, under whioh the tendons pass to the foot, and are thus securely bound down, as a slight glance at the delineation will evince [q].
